Canopus III is a planet in or near Federation space, located in the Canopus system, orbiting the star Alpha Carinae. Lactra VII, presumably in the Lactra system, is several light years from Canopus III.
The USS Enterprise crew discovered a dinosaur on Lactra VII very similar to the dinosaurs native to Canopus III. Tests determined the Lactrans transported the dinosaur for their zoo exhibit. (TAS: "The Eye of the Beholder")
